- plain tablets having a diameter of 7 mm, a weight of 125 mg and a thickness of 2.85 mm were obtained using a rotary tableting machine.
- the hardness of the obtained uncoated tablet was 50N, no poor appearance such as cracking or chipping of the tablet was observed, and the disintegration time using water as a test liquid was 2 minutes, showing rapid disintegration. In addition, this granule showed no change in appearance and solubility even after 6 months.
- the resin composition of the present invention can be used as a coating agent for pharmaceuticals, veterinary drugs, agricultural chemicals, fertilizers or foods.
